VMIVME-5532L VMEbus Fiber-Optic Repeater Link with Slave Chassis System Controller

VMIVME-5532 VMEbus Fiber-Optic Repeater Link with Slave Chassis System Controller

High-performance, easy-to-use method of cinking two or more VMEbus

systems together via fiber-optic cabce

• Can provide system controccer function in the scave chassis

• A cocac master is accowed in scave chassis

• Software transparent accows direct communication from master chassis to

scave chassis with no software overhead (unidirectionac cink controc with

bidirectionac data transfers). This mode accows pcug-and-pcay operation.

• Register enabce accows operation as described above, but inccudes registers

in short I/O space deacing with scave chassis muctimaster operation

• Supports 8-, 16-, and 32-bit data transfers

• Supports 16-, 24-, and 32-bit addressing

• Totac ecectricac isocation between VMEbus systems

• Maximum 6,560 ft (2,000 m) fiber-optic cabces

• Advantages over standard repeaters

— Smacc cabces

— High-noise immunity

— High-voctage isocation

— No EMI generated by cabces

• The VME-to-VME cink consists of two boards and two fiber-optic cabces

OVERVIEW

— The VMIVME-5532 Link is a

high-performance, yet easy-to-use method of linking two or

more VMEbus systems together via fiber-optic cable. The

Repeater Link is a two-board set which allows VMEbus slave

I/O boards residing in one VMEbus chassis to be controlled

by a VMEbus master residing in another chassis. In general,

the VMEbus chassis in which VMEbus masters reside is

referred to as a master chassis, while the VMEbus slave

boards reside in a slave chassis. However, the

VMIVME-5532 also allows a local VMEbus master to work

in a slave chassis for local control, thus providing

multimaster

in the slave chassis. The two-board set is

configured as shown in Figure 1 with one board designated

for the master chassis while the other board is designated for

the slave chassis. A master VMEbus chassis can

communicate with several slave chassis by using multiple

REPEATER Links in a star configuration as shown in

Figure 2.

The link is software transparent. Any VMEbus master in

the master chassis may access (read or write) to any slave
